Landing page CRO for UK ecommerce PPC campaigns

What to take away

A paid click should land on a page built for that adone offer, one audience, one action.
UK price rules apply from the first screen. Show the total a shopper pays and take explicit consent for add-on charges.
Keep only the form fields with a stated purpose, which is also what UK GDPR asks of you.
Judge the page on the resulting order, not the click, and fix the stop date before the test begins.

A paid click is not a browsing session

A visitor from a search ad arrives with one question and very little patience. They came for the thing named in the headline. A full navigation menu, a newsletter pop-up or a carousel of unrelated promotions all compete with that.

Treat the landing page as the middle of a sentence that starts in the ad. The headline repeats the promise, the page proves it, and the next step is one button. A shopper who clicked a paid ad is quicker to leave than one who typed your name.

The UK rules that shape the page

Price claims are where UK advertisers slip most often. The CAP advertising codes require a quoted price not to mislead, and they expect the ad and the page to agree about what is being sold. Google Ads applies its own consistency checks on promotions.

UK price display rules

Compliant page

Quoted price: Not misleading
Ad and page: Agree on offer
Total price: Shown before order
Delivery cost: Stated upfront
Optional extras: Unticked boxes

Non-compliant page

Quoted price: Misleading claim
Ad and page: Inconsistent
Total price: Revealed at checkout
Delivery cost: Added later
Optional extras: Pre-ticked boxes

The Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013 set out what a shopper must see before ordering, including the total price and delivery costs. A page that advertises a headline price and reveals a delivery fee at checkout breaks the rule on additional charges. Pre-ticked boxes for gift wrap or insurance fail the same test.

Both rules point the same way: the page carries the full offer, not a teaser corrected two steps later.

Keep the form short and defensible

Every extra field costs a little conversion, and fewer fields usually mean more completions, so the fields you keep must earn their place. ICO guidance on UK GDPR expects personal data to be collected for a stated purpose and no more, so a field nobody uses is a risk with no upside.

Drop the phone number if nobody calls, and drop the company name on a consumer offer. Where a field stays, label its purpose beside it. Our ecommerce form optimisation notes cover the same ground for sign-up and account forms.

Build it in a fixed order

Build the landing page in order

Freeze ad copy including price or discount
Write headline in the ad's words
Put full price and delivery first screen
Cut competing links, leave one button
Test on mid-range Android throttled connection

Freeze the ad copy first, including any price or discount, so the page has something fixed to answer.
Write the headline in the ad's own words, naming the product, the price and the delivery promise.
Put the full price, delivery cost and returns window in the first screen, before any scroll.
Cut competing links from that screen and leave one primary button.
Load the page on a mid-range Android phone on a throttled connection and fix what breaks.

Match the ad to the page

The table sets out the gaps that show up most often between an ad and its landing page. Treat each row as a hypothesis you can test on its own.

Ad-to-page gaps to test

Weak version

Headline: Brand name and slogan
Price: From-price with small print
First screen: Navigation, banner, pop-up
Form: Phone, company, job title
Next step: Five equal-weight links

Tested version

Headline: Product or offer from ad
Price: Total price with VAT and delivery
First screen: Headline, image, price, button
Form: Fields the next step needs
Next step: One primary button

Weak version

Headline: Brand name and a slogan
Price: A from-price with the qualifier in the small print
First screen: Navigation, banner and a pop-up
Form: Phone number, company and job title for a consumer offer
Next step: Five links of equal weight

Tested version

Headline: The product or offer from the ad, in the ad's words
Price: Total price with VAT and delivery, stated in the first screen
First screen: Headline, product image, price and one button
Form: The fields the next step needs, each with a stated purpose
Next step: One primary button

For ecommerce, the sharpest gap sits at the handoff. A paid click often lands on a product page, and the cues there decide the order. Our product page CRO guide covers that half of the journey.

Measure the order, not the click

Paid search reporting stops at the conversion action, and that action is whatever you tagged. If the tag fires on a form submit rather than a paid order, the page can look excellent while failed payments and returns pile up behind it.

Reconcile the test against order states you can actually see: dispatched, cancelled, refunded. Read the result across a full week so weekday and weekend behaviour both appear. PPC landing page optimisation is a page-level job with an order-level verdict.

Common questions

Does every campaign need a dedicated landing page?

Not always. Where a campaign sells one product, its page can serve as the landing page if it repeats the ad's promise and shows the price without a scroll.

Can the ad and the page show different prices?

No. A page showing a higher price than the ad invites a complaint under the CAP codes and a platform disapproval, so pause the ad if the price has changed.

How long should a landing page test run?

Long enough to cover a full purchase cycle and both weekend and weekday traffic. Set the sample and the stop date first, and do not stop early because the opening days look good.
